IMPROVEMENT IN SELF-OILIG CAR-WHEELS.

Specification forming part of Letters Patent No. 202,581, dated April 16, 1878; application filed v March 14, 1878.

To all whom it may concern:

Be it known that I, THOMAS H. PHILLIPS, of Orwin, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in SeltOiling Car Vheels; and 'I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The nature of my invent-ion consists in the construction of a self-oiling car-wheel; and has for Aits objectl to retain' the oil, and allow of the wheel being easily removed, when required, and another substituted, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains `to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 isa central vertical section of my Figs. 2, 3, 4, and 5 are enlarged detail views of parts of the same.

A represents a car-wheel, of which B is the hub, said hub being formed with an interior oil-chamber, C, having inlet a on the outer side of the wheel, and outlet bwithin the hub, for the passage of the oil to the axle. In each end of the hub B are cast a Sufficient number of openings or recesses, d d, of any suitable shape, into whichrare driven wooden plugs e e, so as to bring them flush with the face of the hub.' On each end of the hub are also cast two or more projecting lugs, IL h.

A rubber or other suitable packing, k, is then placed 011 the end of the hub, which is kept in place by means of an iron washer, D, havin g suitable notches for the passage of the The washer D is drawn down tight by means of common woodscrews i z', which are screwed into the wooden plugs e e, said Screws having their heads countersunk in the washer, so as to be flush with its face. The lugs h h take all the Strain from the screws in the revolution of the wheel.

rlhis device is very simple and cheap, and can be adapted to any pattern of wheel without necessitating any change in the axle. I use thc ordinary axle F, with' collar m and linchpin n.

The wheel has free lateral motion on the axle. In case of breakage or accident the wheel may be removed by the simple withdrawal of the linchpin and a new wheel put in, and this is a very important feature-no bolts or springs of any kind to get loose or out of order, and thus interfere With its oiltight qualities.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a car-wheel, the hub B cast with recesses d in each end to receive wooden plugs e, for the purposes herein set forth.

2. The combination of a car-wheel having Wooden plugs e driven into holes or recesses in the ends of its hub, the packing k, washer D, and wood-screws i, substantially :is and for the purposes herein set forth.

3. In combination with a car-wheel having a metal washer, D, secured upon each end of the hub by wood-screws, as described, the lugs or projections It h cast on the hub and fitting in notches in the Washer, substantially as and for the purposes herein Set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses. A

THOMAS H. PHILLIPS.
